Guitar Hero 5 not running

i put in the disk, go through HBC to NeoGamma, change my region over to force NTSC480i(its what i do for all of my other PAL isos). then, when i run game from DVD, it flips green(usual) and just goes black. i have Wiimote power, but nothing happens. game does nothing but black, and Wiimote does nothing but flashes. i have to hold power button to restart system.
any clue why i can't play this game?
please help...
please?

oh, thanks. i got it figured out, i had another wad that i had to install.
id found a tut on a different forum site, and didn't remember where i posted this. lol
but yeah, i got it running, from disc and HDD.
note: the frontman guitar controller that looks like an old telecaster, works on guitar hero and rockstar

seriously, i don't remember what order i installed what. i just know that i used the bannerbomb method to everything. i know for NeoGamma, i had to instal Cios 247...but honestly, there are probably more people that know a lot more about it than i do. i just did my Wii so i wouldn't have to worry about my kids scratching disks. my psp, i know more about.

oh, if you were talking about how i got GH5 to work, it was a fix that i found. i don't remember the website i found it on. i don't remember what the download itself was called, but the .rar is AddersGH5packrar.rar.
